BRICK-CUTTING MACHINERY.

Specication of Letters Patent.

Patented Sept. 24, 1907.

Application filed March 24,1905. Serial No. 251,853.

To all whom it may concern:

Be it known that I, ANDREW RAMsAY, a subject of the King of Great Britain, residing at Mount Savage, in the county of Allegany and State of Maryland, have invented new and useful Improvements in Brick- Cutting Machinery, of which the following is a specification.

This invention relates to brick-cutting machinery.

In brick-cutting machinery an element thereof is known as board delivery tables, which are adapted to receive the bricks and from there are transported te the drying department through the means of pallets. These pallets are generally constructed of wood or sheet iron, but it has been found dilicult to keep the wood pallets from warping and to get the sheet-iron pallets true and level on surface. y Consequently when into which one or more pallets is or are deposited, the

slots being of such depth that when the pallets are mounted therein, they are below the surface of the holder, so that when the pallet or pallets is or are lifted up, it or they will carry the bricks therewith. The bricks are then transported to the drying department and another pallet, or pallets, dropped in the slots, and the operation repeated. l

The invention further aims to construct the palletholder and pallets in such manner as to provide means whereby when the bricks are delivered upon the holder or the pallets, the entire bottom surface of the bricks is not in engagement throughout with the holder and pallets; consequently, enabling a certain amount of evaporation to be had and thereby obtaining quickerv drying, which is desirable.

A further object of the invention resides in the construction and arrangement of the delivery table, whereby the said table will be independent of the cutting table, and so that the said table when set up and operated will not be in the way of the wire-holder, which has been found to be objectionable. To this end 'the delivery table is not attached to the cutting table but travels upon a suitable support, and the said delivery table is adapted to be moved towards and away from the cutting table in a manner as hereinafter referred to.

A further object of the invention consists in the construction, arrangement and operation of the cutting wires agid their support, such wires being so positioned and operated that during the cutting o'f the clay., they will move downwardly substantially in the arc of a circle, thereby cutting through the clay at an inclination which not only facilitates the cutting operation but also makes a clean cut.

With the foregoing and other objects in view, the invention consists of the novel combination, construction and arrangement of parts hereinafter more specifically described, illustrated in the accompanying drawings, Which form a part of this specification, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail, reference is had to the accompanying drawings, wherein like reference characters denote corresponding parts throughout the several views, and in which:

Figure 1 is a side elevation, showing portions of a brick-cutting machine in accordance with this invention, and Fig. 2 is a plan view thereof.

Referring to the drawings by reference characters, the delivery table is formed of a reciprocatory support and removable pallets. The support is termed a pal-p let-holder7 and consists of a lower section I and an upper section 2. The lower section l travels upon the supports 16d of the cutting table 4. Said base is provided at each side with an elongation so that the said section l can travel thereon. The section 1 carries the rollers 5 which rest and travel upon the support 16d.

The upper section 2 is formed of a series of vertical members connected together by transversely-extending members. The vertical members are spaced apart so as to form the slots 6 into which are placed the pallets 7. The bars and uprights which form the section 2 are cast so that the upper surface thereof will be straight and even, and the uprights 2 are fixed to the section l in any suitable manner. The pallets 7, as shown, are cylindrical in cross-section, but can be of any suitable contour, and the said pallets 7 extend outwardly from each side of the section l so that they can be readily grasped and removed from the palletholder carrying the bricks therewith. The height of thepallet-holder .is such that the upper surface of the transverse bars which form a part of the section 2 will be-in alinement with the upper surface of the cutting table 4. That end of the section l which is arranged adjacent to the edge of the cutting table is cut away, as at 8, seas to form a clearance for the Wire-holder, to be hereinafter referred to. The supports 16d of the cutting table carry a plurality of rollers 9 which travel upon the track l0 so that the said cutting table can reciprocate and have the said reciprocations thereof associate with the reciprocations of the pallet-holder in a manner as hereinafter referred to. Thereciprocation in one direction of the cutting table is to shove thercut bricks therefrom and upon the pallet-holder. The cutting table 4 is provided with a series of slits 12 to per'- mit of the passage of the cutting wires, to be hereinafter referred to. The track l0 is secured to the base 3 of the machine and at each side of the base 3 an upright 3n is arranged, said uprights being connected together at their' tops by the shaft 3l.

The reference character 12:L denotes the rearward cutting wire-holder secured between a pair of toothed quadrants 161L and to which the rear ends of the cutting wires 15 are attached. The forward cutting wire holder is indicated by the reference character 13 and which is provided with a series of clamps 14 to which forward ends of the cutting wires 15 are connectedy there being as many cutting wires 15 as there are slits 12 in the cutting table. The wire-holder 13 is adapted to have an oscillatory movement imparted thereto so that it will cause the cutting wires to move substantially in the arc of a circle, thereby cutting through the clay 13XL at an inclination which not only facilitates the cutting operation, but also makes a clean cut. The other end of the cutting wires is suitably connected to a support, not shown, the connection being such that the necessary movement of the cutting wires during the vcutting operation will not be retarded in any manner.

The normal position of the cutting wires, that is to say, before the cutting operation is such that they extend over the top of the clay and in parrallelism therewith, so that when the wire-holder is oscillated, the cutting Wires will travel substantially in the arc of a circle and cut in an inclined manner through the clay.

The wire-holder 13 is supported upon two doublecrank arms 16, one arm of each of such double-crank arms 16 arranged exteriorly of the support 16d and the other arm of which is arranged interiorly of the support 16d7 and the said double-crank arms are connected to the toothed quadrants 16L supported upon the shaft 3l. The quadrants 16 mesh with a pair of toothed quadrants 16LL mounted upon the shaft 16L journaled in the base 3 of the machine. The supports 16l of the table are each formed with a substantially L-shaped slot 16e, one branch of said slot being longer than the other, the elongated portion extending in the arc of a circle and the other portion extending vertically at an inclination. Projecting into each of the slots 16c is a roller 16f. There is a roller 16i connected to each of the Asupports 16d and fixed to each of the quadrants 16. An operating lever 161 is connected to the shaft 16c for actuating it so that when the lever 1611 is pulled towards the rear of the machine the shaft 16c is rocked in o ne direction so that the quadrants 16b are carried rearwardly with the shaft 167 and, owing to the meshing of the quadrants 16') with the quadrants 16, these latter will have a downward movement imparted thereto. During the operation of the quadrants 16n the rollers 16f move through the elongated portions of the slots 16e until the rollers reach the point. 16?, when, on a further movement of the quadrants 16l` and owing to the engagement of the rollers 16f with the wall of the vertical portion of the slots 16@7 the table is caused to move rearwardly until the forward end of said table is in alinement with the forward face of the abutment 20. Owing to the rearward movement of the table 4 and in connection with the abutment 20, the bricks7 when the forward end of the table 4 is in alinement with the forward face of the abutment 20, are then transferred to the section 2. On reversing the movement of the quadrants 16n the rollers 16f engage the wall of the vertical portion of the slots 16e and move the table back until the said rollers pass the point indicated by the reference character 16j, when by this time the table will have returned to its original position. Further upward movement of the quadrants I6" is allowed by the passage of the rollers 1.6f forwardly in the elongated portions of the slots 16". Owing to the manner of constructing the slots 16" the elongated portions are in the are of a circle and consequently the table t willbe stationary until the rollers 16I reach the point l6i or pass the point 161', as hereinbefore referred to. Therefore. the table cannot move back until the rollers t6f are at the point 16i owing to the fact that the rollers 16 travel in the saine arc as the elongated portion of the slots lt". By such construction the table -1 is retained stationary while the bricks are being cut; otherwise if the table 4. moved the bricks would be partially delivered bev fore they were cut. When the operator grasps the handle 16h and throws the same back motion is transmitted through the shaft 16c to the quadrant 16"7 t6, so that the wire holder 13, which is connected to the quadrants 16*L will move downwardly. The wire holder l21L will also move in the same direction. When the quadrants 16 are moved in an opposite direction the wire holders will be returned to normal position. At the commencement of the cutting (nreiations the wires 15 will extendlat the angles shown in the drawing owing to the fact that thel wire holder 13. when in normal position7 is arranged above the wire holder l2. the latter being on a level with the face of the brick. As the quadrants 16a move downwardly and inwardly the wire holders move therewith and carry the cutting wires so as to cause themto first pass through the brick parallel with the tace thereof` after which the cutting Wires move douf'nwardly and lrackwardly, thus securing an easy and clean cut.

The inner arm of each of the double crank arms 16 is connected through the medium of the pivoted link 17 to the section 1 of the pallet-holder. said link being curved and connected, respectively, to the crank arm and support. as at 18, 19. Such connection between the arms 16 and the section l, ilnlrarts a reciprocating movement to the said section 1 when the wireholder is operated. The connection is such that when the wire-holder 13 reaches a position below the table l1, the section 1 will be drawn towards said table 4. and as soon as the said section 1 is in close proximity to the table 4. the base 3 of the said table is moved with the said section 1 and the bricks are shoved upon the pallet-holder. A suitable abutment is provided to cause the shoving of the bricks off the table 4, as it moves with the pallet-holder, upon the pallet-holder. When the wire-holder 13 is moved in an opposite direction, the table 4t, through the medium of the mechanism which reciprocates it is caused to assume its normal position. and the connection.between the crankarms 16 and the section 1 of the pallet-holder, causes the said pallet-holder to be moved in an opposite direction. When the palletliolder has arrived at the end of its movement, the pallets are lifted out of said holder, carrying the bricks therewith` and the bricks are then transported to the drying department. '.lhe cut-away portion oi the section 1, as before stated. forms a clearance space, said clearance space adapted to permit of the downward movement of the wireholder 13.
